From Christchurch BMW (Jeff Grays)
Its not all that cheap, but importing one isn't either due to the freight cost.
Misfire, well it hasn't done it again, did 1000ks in the last 2 days going on a road trip.
But it idles a bit rough when cold, i have a new coil coming, i'll replace the one on Cyl #4 and see if it helps.
